It didn't look like my bearing was going to fail immediately. The seals looked fine from the outside, but they had in fact been compromised. There was no grease in the bearing, just a bit of oil and the IMS shaft was full of oil. There was a bit of wobble in the bearing from wear. So although it didn't look like it was going to fail soon, with the seal compromised and poor lubrication I imagine it was just a matter of time. I think exposure to the hot oil in the sump really does those seals in. In comparison the pilot bearing on the flywheel was just as old, but when I removed the seal from it just to look I found it packed with clean, lifetime grease. The difference - the environment where the seal and bearing sit. No oil or excessive heat at the center of the flywheel...
